I have had a number of Briggs and Stratton quantum mowers that have had split seams in their plastic fuel tanks. It is always around the seam on the engine side. I have tried "plastic welding" with a soldering iron and some scrap plastic. This was unsuccessful or just temporarily successful and may have failed because the two plastics have to be exactly the same. However, I had a friend who said he had his son try and do this and it also failed and he was a professional plastic welder.

I have tried hot melt glue, also a temporary success, I've tried an epoxy mixture that is very strong and works under water etc-too I think it was too rigid and the seam opened up again. I have also tried one of the permatex gasket products and it was totally useless. So I was wondering if any body has had a successful repair on a plastic fuel tank seam and, if so, can they share it with me.
